As seen in Figs. 2 and 3, the arm 20 is carried by a slide 21 on which the guide 22 fixed to the frame of the machine moves vertically. The slide has gear teeth 23 with which aworm pinion, not shown, meshes, the pinion being rotatable by a suitable tool for raising and lowering the frame of the binder relatively to the axis of the caster wheel. This feature forms no part of this invention and is standard to hinder construction. The axle 1 1 is fixed to a slide on which moves a' guide fixed to the frame, similar to standard makes of horse drawn binders. V

The arms 18 and 20 form a fork in which the caster wheel 4 normally extends when the machine is traveling in a straight line.

1 Owing to the arrangement of the arms 18,20 and the axis or spindle 2 of the caster wheel, there is no sidewise binding of the slide 21 in the guide when the caster wheel is in its normal position.

When castering, the arm 18 swings on its pivot 19 and when used as a steering wheel the arm 18 and wheel 4 are swung into the position shown in dotted lines in Figs. 1 and 3.

The means by which the caster wheel is operated as a steering wheel includes a socket 24L mounted on the arm 18' and arranged to receive a tiller pole 25 which, when the caster wheel is positioned to be used as a steering wheel, extends within reach of the seat 26 of the binder. I

In operation, when it is desired to move thebinder sidewise, the steering wheel 5 is turned into an angular position by turning the steering rod 7 and is locked in such position as the worm 8 and spiral gear 9 are self locking.

The tractor wheel .6 is also turned and held in an angular position by suitable means such as described in our Patent No. 1,247,073, dated Nov. 20, 1917, and during the movement of the binder sidewise it can be steered by means of the caster wheel 4 and tiller pole, 25. p r 7 What we claim is: y

1. In an agricultural machine, a frame, steering and tractor wheels supporting the frame, and a caster wheel at one side of the frame. the steering and tractor wheels being shiftable into positions at. an angle to the normal line of travel of the machine, and means for operating the caster wheel as a steering wheel when the steering wheel and tractor wheels are in angular positions, substantially as and for the purpose described.

2. In an agricultural machine, a main frame, having a steering wheel atone end,

a tractor wheel at its other end shiftable about an upright axisinto an angular position parallel "to *an angular position into which the steering wheel is 'shiftable, an implement frame supported by the main frame and ihaving'a caster whee]. at-one side, and means for operating the caster wheel as a steering wheel, Substantially as and for the purpose specified. I

3. In an agricultural machine, a main frame having a steering wheel at its front end and atractor wheel at its, rear end, said wheels being shiftable into angular positions relatively to the normal line of travel of the frame, an implement comprising a frame-mounted on the main frame and having a caster wheel at its outer side, and means for manually operating the caster wheel to operate the same when the steering wheel and tractor wheel are set in angular positions, substantially as and for the. purpose set forth. a

4. An agricultural machine having a caster wheel, a support for the caster wheel comprising a fork including a horizontally extending arm, and. a second horizontally extending arm pivoted to the first arm and carrying a spindle at;its free endon which the caster wheel is mounted, said arm being movable freely on its pivot, substantially as and for the purpose set forth.

5. An agricultural machine having a casterfwheel, a support for the caster wheel comprising a fork including a fixed :h0ri- V the purpose described.

,6, In anagricultural machine, a frame, front and rear wheels supportingthe main frame and shiftable in angular positions relatively tothenormal line of travel, a wheel at one side of the frame, and means for operating the last mentioned wheel, as a steering wheel,when,the front and rear wheels are set in angular positions, substantially as and for, the purpose specified.

7. An agricultural machine having a caster wheel, asupport for the caster wheel comprising a fork, including a fixed horizontally extendingarm, and a second horizontallyextending arm; pivoted to the first arm and carrying a spindleat its free end on which the caster wheel is mounted, and

means for moving the second arm on its e 8. In an agmc iltural maehine, threaten? sition totravel in tially as and for the purpose described.

In testimony whereof, we have hereunto signed our names at Syracuse, in the county of Onondaga and State of New York, this 24th day of June, 1919.
